CYENTRIFUGAL LIQUlD-SEPARATOR.

Patented Feb. 13, 1906.

Application filed November 3,1904. Serial No. 231,306.

To all whom, it may concern:

son, a subject of the King of Sweden and Nor- Be it known that I, ALeoT LEVIN CHRISTEN- way, and a resident of Stockholm, Sweden, have invented new and useful Improvements in Distributing Devices'for Centrifugal Separators, of which the following is a specification, reference being had-to the drawings accompanyingand forming a part hereof.

This invention relates to a distributing device for such line'rs for centrifugal separators which consistof conical plates superposed on one a another.

The object of the invention is to provide a simple and reliable distributing device which will be able to evenly distribute the full-milk between the plates of the liner.

The invention consists, chiefly, in the com- .bination,-with the conical plates constituting the liner, of means for preventing the tangential ofi-flow of the full-milk and to create a counter pressure at the place or places where plates on'line E F the full-milkis introduced in the spaces between the plates in order to compel the fullmilk to rise along liner and evenly, enter allthe spaces of the same. The said means may consist of one or more walls or the like extending axially'or principally axially through the bowl and intersecting the liner at the inner part of the same and being so placed in relation to the direction of rotation of the bowl that they act it; theblades of a centrifugal pump or the In the accompanying drawings I have I e 1 shown s'ome liners embodying my invention,

. Figure 1 shows a vertical section on line C D in Fig. 2 of a centrifugal separator-bowl having a iner oi the kind set forth. Fig. '2 shows a horizontal section on line A B in Fig. 1. -Fig. 3 shows a vertical section of some in Fig. 2. Figs. 4, 5, 6, 7, S, 9 and 10 show modifications.

Referring to Figs. 1 to 3, each plate 1 is at the inner edge provided with one or more notches 2, placed above each other, so as to form one or more axially-running distributing-channels. Atthe rear side in relation to the direction of rotat on of the bowl (indicated by the arrow in Fig. 2) the said notches may be provided with ribs 3 or the like of preferably the same height as the distance between the plates. The said ribs 3, together with the intermediate edges of the plates, formwal'ls limiting at the central inlet pipe the wholeheight of the one side the (11S.-

tributing-channel formed by the said notches 2. For introducing the tull-milk intothe bowl may in well-known manner be used a central inlet-pipe .4, communicating at the lower end with a channel (or channels) 5, provided at or, as is shown, in the bottom of the bowl. The outer ends of the said channel 5 may be arranged below the lowerend of the distributing-channel formed by the notches 2.

The distributing device described above works as follows: The full-milk le-t into the t flows out through the channel 5 and strikes the wall formed by the said ribs 3, and the intermediate edges of the plates 1, spreads itself along the said wall, and enters thereupon into the spaces between the plates 1, the distribution of the fullmilk along the said wall depending, essentially, on that the latter on account of their oblique position act as the blades in a centrifugal pump or the like, and thereby cause a counter pressure against the outflow of the full-milk in the spaces between the plates. The said counterpressure will to a certain extent prevent the flowing off of the milk through the lower part of the liner, through which the larger part of the milk would otherwise flow, thereby causing a uniform distribution of milk in the liner.

The device illustrated in Figs. 1 to 3 may be modified in many ways from the principle of the invention. Thus, for instance, the wall or walls formed by the ribs 3 and the intermediate edges of the plates may be obtained by bending up (or down) the one edge 6 of the notches 2, as is shown at the uppermost plate 1 in Fig. 3. The channel or channels formed by the notches 2 may further be lim ted at the one side by a plate 7 or the like, extending along the whole height of the liner, as is shown in Fig. 4. The wall limiting the channel or channels formed by the notches 2 need not be plane, but may be made of curved or angle-shaped horizontal section, as is illustrated in Fig. 5.

In the modifications illustrated in Figs. 6 and 7 the notches forming the axially or aproximately axially running channel (or channels) are dispensed with. In this case the ribs 8 .or-the like on the plates 9, Fig. 6, may extend beyond the inner circumference of the plates, or ribs 10 on the plates 11, Fig. 7, may extend outward from the outer edges of the usual wings 12 of the central inlet-pipe 4. n

the first-mentioned case the iull-milk will rise without departing along the parts of the ribs 8 extending beyond the inner circumference of the plates 9, while in the modification shown in Fig. 7 the fullmilk, on account of the counter pressure caused by the ribs 10, will be compelled, to r se along the wings 12 of the central inletpipe 4.

Instead of the inlet device illustrated in Figs. 1 and 2 I may make use, for instance, of an inlet-pipe having radially or approximately radially extending slotted flanges, as shown in Fig. 9,vor of any other kind of inlet devices, as will be easily understood by those skilled in the art.

The devices described above may finally be modified in such manner that the wall or walls effecting the counter-pressure against the outflow of the milk are placed inclined in relation to ahorizontal plane, as shown in Fig. 10, so as to facilitate the upward movement of the full-milk and in such manner that the said wall or walls are made wider in radial direction at the lower part of the liner than at the upper part of thesame, as shown in Fig. 8, in order to effect a counter-pressure decreasing toward the top of the liner.

Having now particularly described my invention and in what manner the same may be performed, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a centrifugal separating-bowl and a liner therein consisting of conical plates superposed on one another, of walls extending axially through the bowl and being placed obliquely in relation to a radius, and means for introducing the full-milk in front of the said walls in relation to the direc tion of rotation of the bowl, substantially as and for the purpose set forth.

2. The combination with a centrifugal separating-bowl and a liner therein consisting of conical plates superposed on one another, of imperforate walls extending axially through the bowl and intersecting the liner at the inner part of the same and being placed obliquely in relation to a radius, and means for introducing the full-milk in front of the said walls in relation to the direction of rotation 1 of the bowl, substantially as and for thapurpose set forth.

3. The combination with a centrifugal separating-bowl and a liner therein consisting of conical plates superposed on one another the saidplates having notches at their inner parts forming axially-running distributing-channels, of imperforate walls limiting the rear sides of the said channels in relation to the direction of rotation of the bowl, the said walls being placed obliquely in relation to a radius,and means for introducing the full-milk in front of the said walls in relation to the direction of rotation-of the bowl, substantially as and for the purpose set forth.

4. The combination with a centrifugal separating-bowl and a liner therein consisting of conical plates superposed on one another, the said plates having notches at their inner parts forming together axially-running distributing-channels, of imperforate ribs on said plates placed at the rear sides of said notches in relation to the direction of rotation of the bowl and in alinement with each other so as to form together with the intermediate edges of the plates walls extending axially through the bowl, and means for introducing the fullmilk in front of the said walls in relation to the directionof rotation of the bowl, substantially as and for the purpose set forth.

5. The combination with a centrifugal separating-bowl and a liner therein consisting of conical plates superposed on one another, of

a central inlet-pipe having longitudinal wings,

imperforate walls intersecting the liner at the inner part of the same and extending outward from the outer edges of the said wings obliquely to a radius, and means for introducing the full-milk in front of the said walls in relation to the direction of rotation of the bowl, substantially-as and for the purpose set forth. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
